BABBITTING MACHINE.

Application filed Octoberl'i', 1921. Serial No. 508,329.

To aZZw/wmz'tmw-y concern: I

Be it known that I, Monnrs l3. Mosrn, a citizen of the United States,residing at Wells, in the county of Faribault and State of lliinnesota,have invented certain new and useful Improvements in BabbittingMachines; and I do hereby declare the tollowing to be a full, clear, andexact description 01" the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention has for its object to provide a highly etlicient andaccurate babbitting machine intended for general use, but especiallyadapted for use in forming babbitt bearings in the connecting rods ofmultiple cylinder combustion engines.

To the above end, the invention consists of the novel devices andcombinations of devices hereinafter described and defined in thedrawings. i

In the accompanying drawings, which illustrate the invention likecharacter sindicate like parts throughout the several views. 1

Referring to the drawings:

vertical section taken on the line it-4: oi: Fig. 1-3, with the top andbottom core plates inverted in respect to their. position sh vn in Fig.2; l

Fig. 5 is a View partly in end elevation and partly in transverse"vertical section showing a modified form of mold and also showing aclamping attachment for the mold; and i l Fig. 6 is a fragmentary planview of the parts shown in Fig. 5.

The babbitting machine illustrated includes a skeleton frame havingsubstantially A-shaped end members 7 connected by. upper side bars 8and? a bottom shelf .9. A

long narrow table 10 ismounted on the frame end members 7 for angularlateral tilting adjustment by providing said table, at its ends, withdepending lugs 11, which are pivotally connected to bearing brackets 12on said frame end members by a long clamping rod 13 which extendsthrough aligned bores in said lugs and bearing brackets, andprovided'with a niit actii1g hand wheel 1%. To positively hold'the lugs11 in different adjustments on the bearing brackets 12, said lugs andbearing bracl ets are provided withserrated surfaces 15 011 theiropposing faces. a a y A horizontal turntable 16, having hinged top andintermediate sections 17 and 18, respectively, is secured to the top ofthe table 10 at its inner end by a nut-equipped pivot bolt 19. The topsection 17 is hinged at 20 to the turntable 16 and loosely rests on thehead of the pivot bolt 19, andthe interme diate section 18 is hinged at21 to said top section 17 at a point diametrically opposite.

and. rigidly secured to a pair of laterally spaced transversely extendedblocks 24, which, in turn,- are rigidly secured to the top section 17.The other or outer end of the track rail 23 is supported in the fork 01"a. bifurcated bracket 25 attached to the outer end of the table 10. Ahookracting spring 26, attached to the bracket, (see Fig. 1), isarranged to releasably engage the track rail 23 and yieldingly hold thesame on the bracket 25. I

At the inner end of the track rail 23 is a horizontal face plate 27having a depending hub 28mounted in a collar 29 rigidly secured to theupper ends of a pair of upright arms 30 having, on their lower ends,sleeves 31 secured to the ends of a horizontal cross-bar byscrew-threaded engagement. This cross-bar 32 is intermediately securedto the inner end of the track rail 23 by a nutequipped stuc 3 :3. Thumbscrews 34: prevent the sleeves 31 from turning on the cross-bar andwhich cross-bar is provided with reduced end extensions 35, for apurpose that will presently appear. A'set screw 36, havingscrew-threaded engagement with the collar 29 and hub 28, prevents theface plate 27 from turning on said collar. On the upper surface of theface plate 27 are conccmtric work-positioning; rings 3'7.

In Figs. 1 to l, inclusive, the machine is shown adjusted and providedwith the necessary mold for forming a babbitt bearing in thecrank-receiving end or of a connecting rod y, and which end, as shown,comprises half sections connected by nut-equipped bolts The other orwrist-pin-receiving end of the connecting rod 1 is indicated by theletter a. i

In this adjustment of the machinepthe mold includes a core sleeve,around which the connecting rod end is positioned. The core sleeve 88 issecured to the intermediate portion of a spindle 3 The mold furtherprovides upper and lower annular core plates 40 and 421, respectivelyhaving axial openings through which the ends of the" spindle 39 project.These core plates -10 and d1, are adapted to rest upon the ends of thecore sleeve 38 and close the ends of the connecting rod end w, as shownin Fig. l.

' The lower end of the spindle 39 is removably mounted in a bushing 42mounted in the hub 28 of the face plate 27 and held by the set screw 36with the bottom core plate ll supported on saidbushing and the face 4plateQY. l-lemovably mounted on the upper face plate 4:0 is a hopperflange or skimming cup as into which molten babbitt is poured, and fromwhere it flows through apertures Min the top core plate 10 into thespace between thecore'sleeve 38, connecting rod-receiving end and topand bottom core plates a0 and ell. One of the faces of each core plateetO and 1 1 is smooth and the other face thereof has formed therein anannular groove 45. \Vhen the faces of the core plates 40 and 41.,havingthe annular grooves lfi, are turned toward each otheri as shown inFig. 2, the babbitt bearing will be formed with beads which overlap theends of the connecting rod end By inverting the core plates 4:0 and allto turn their smooth taces toward each other, as shown in Fig. l, thebabbitt bearing will be formed flush with the ends of the connecting rodend a The connecting rod end is held by an upright spindle ell-6, whichextends therethrough, as best shown in Fig. l, and is of the samediameter as the wrist pm to which the connecting rod is to be applied.The

lower end of the spindle 46 is removably mounted in a socket 417 havinga base 48 pro vi (led with a pair of transversely aligned trunnions 49journ'aled in upstanding bearings 50 on the sides of a traveller 51;This traveller 51 is in the form of a'sleeve square in cross-section andslidably mounted on the track rail 23 for movement toward and from thespindle 394 By making the track rail 23 and traveller square incross-section, said traveller is held on the track rail 23 againstturning movement.

To secure the spindle d6 in different angular positions in respect tothe traveller 51 and parallel to the spindle 39, there is pro isprovided for holding the traveller indifferent positions on said trackrail;

To set the axis of the spindle 46 at predetermined different distancesfrom the axis of thespindle 39 for holding the connecting, rod y toreceive a babbitt bearing in the end 00, the" axis of whieh is thecorrect distance from the axis of its end .2, there is provided asquarerotary scale bar 5% having in its edges notches 55 with any one ofwhich a pointer 56 on the traveller 51 is arranged to enter by aspringing movement. This scale bar 5-il extends parallel to thetrack'rail 23 and has, at its ends, trunnions 57 mounted in bearings 58011 one side of said table. In actual practice, the scale bar 54; willhave indicated thereon, at each notch 55, an identi- 'iication mark forassisting the operator in setting the spindle 4:6, for holdingconnecting rods to receive a babbitt bearing the axis of which is thecorrect distance from the axis ofits other end. These identificationmarks may be thenames of the engine, or the automobile for which theconnecting;- rods areintended; or they'may indicate different lengths ofconnecting rods. A shallow annular pan 59 is removably supported on theperipheral edge portion of the face plate 27 to catch any babbitt metalwhich may be spilled at the time ofeasting.

To heat the parts to which a babbit-t beau ing is to be applied and themold, an ordinary blow torch 60 is used, as indicated in Fig. 1. Thisblow torch 60 is supported from the frame of the machine iliOlflGItlCilland horizontal adjustment by rigidly securingthereto a depending stem 61turnably and endwise movably mounted in a bearing 62 on the outer end ofa two-part arm 63, the members of which are telescopically connected andheld in diiferent longitudinal adjustments by a set screw 64. Aset-screw 65 also holds the stem '61 in vdifferent"adjustments in thebearing 62. On the innerend of the arm 63 is a bearing 66 turnablymounted one spindle 67 with freedom for vertical adjustment and held bya set'screw (38 in different adjustments thereon. The spindle GT iscarried by a bracket 67 on the adjacent frame end member? i "To formindependent half babbitt bearings for the two-part-connecting rod end00, divider-acting shims (39 are interposed between the members of saidconnecting rod end and held by the bolts 0;. These shims 69 engage thecore sleeve 38 at diametrically opposite points and hold the connectingrod y against pivotal movement on the spindle 46 withits end asconcentric with said sleeve. \Vhen a babbitt bearing is castrin aconnecting rod having a single piece end, the concentric rings 37greatly assist the operator in positioning said end on the face plate 27concentric with the spindle 39. After a babbitt bearing has set, aspanner wrench, not shown, is applied to the hopper flange 4L3 andturned. The metal in said flange and on the core plate 40 will locksaidflange and plate together so that the top plate 40mm turn with thehopper flange 43 and thereby shear the metal at the inner ends of theapertures at, which is the weakest point. The hopper flange as and topcore plate 4:4, together with the waste material therein, may then belifted from the spindle 39, which is made easy by tapering said spindle.The spindle as may be set the correct distance from the spindle 39 bymeans of a templet or a connecting rod. and after one set, babbittbearings may be cast in any desired number of connecting rods and eachthereof will be identical, the one with the other.

The machine has been described as used in casting a babbitt bearing in aconnecting rod from one end thereof. For some connecting rods, it isdesirable or necessary to pour the metal into the crank-receiving endthereof through a radial opening therein while the connecting rod isheld in an upright position.

To thus cast a babbitt bearingQthe spring hook 2G is operated to releasethe track rail 23 and then operate the turntable 16 a onehalf revolutionand thereafter move the intermediate turntable section 18 on its hinge20 to carry the parts mounted thereon into the positions shown by brokenlines in Fig. 1.

To cast a babbit bearingin the crank receiving end of the connecting rodthrough a radial opening while said rod is held in a horizontalposition,the. handwheel 1a is operated to release the table 10 and permit thesame to be turned to either side of the frame as indicated by brokenlines in Fig. 2.

In Figs. 1 to a, inclusive, the machine is provided with a mold forcasting babbitt bearings directly in connecting rods. In

Figs. 5 and 6, said machineis provided adapted to receive and hold thelower end ofthe core box 7 O concentric with the core. sleeve 71.

Supported on the upper end of the core sleeve 71 is a top core plate 75having an axial opening through which projects a stem 76 secured in theupper end of the core sleeve 71 and axially aligned with the stem 7 3.()n the periphery of the core plate 75 is an annular flange 77 adaptedto receive the upper end of the core box and hold the same concentricwith the core sleeve 71. A 'hopper flange 78 is removably telescopedonto an extended central portion of the top core plate 75. Molten meta-lpoured into the hopper Hang-e78 will flow into the mold throughapertures 79 in the top core plate 75. To hold the several parts of themold shown in Figs.5 and 6 in assembled relation, there'is provided aclamping attachment comprising a pair of upright anchor .bars 80attached to the bar extensions 35 by forming in the lower ends thereofeyes 81, through which said extensions project,

and are secured thereto by thumb screws 82.

In the upper end portions of the anchor bars 80 is a multiplicity oflongitudinally spaced holes 83 adapted to removably hold a pair sides ofthe cotter pins 84 to connect said bar 85 thereto. Carried by theclamping .bar 85 isfa pair of clamping screws 86 which impinge againstthe top core: plate on each side of the stem 76 and hold the severalparts of the mold assembled.

After the Babbitt metal has set the same is sheared in the apertures 79byturning'the hopper flange 78' with a spanner'wrenc-h, as previouslydescribed.

To form the babbitt hearing A in two parts, thin divider blades 87 areinterposed between the core box members and engage the core sleeve 71 atdiametrically opposite points. In case the babbitt bearing sectionsstick in the core box 70, the same may be pressed therefrom by screws 88which have threaded engagement with the sections of said core box.

Referring again to the machine as shown in Figs. 5 and 6, the hoppersleeve 78 is provided with a plurality of internal upright grooves 7 8into which the metal flows to positively prevent said sleeve fromslipping on the metal when turned to shear the metal at the inner endsof the apertures 79. A stop pi11'7" is secured to the frame '7 andarranged to be engaged by the track rail 23. andhold the same in anupright position when the face plate 27 isturned into a verticalposition shown broken lines in'Fig. 1 e i i T During the heating of theconnecting rod and the mold, the trat'ellerol must be loose on the trackrail 23 so as to move during the expansionof the connecting rod toprevent bendingof the same. i

In case the connecting rod has been bent, one end thereof may be placedover the core sleeve .88 and the other end over the. spindle A6, andthus held While being straightened; l i
